Holm 15a Supermassive Black Hole 40 Billion Times The Mass "we use orbit based, axisymmetric schwarzschild models to analyse the stellar kinematics of holm 15a from new high resolution, wide field spectral observations obtained with muse at the vlt. we find a supermassive black hole (smbh) with a mass of (4.0 ± 0.80) × 10 10 solar masses at the center of holm 15a," the researchers wrote in their paper. Apparent size (v) 1.3 moa. other designations. abell 85 bcg, pgc 2501. holmberg 15a (abbreviated to holm 15a) is a supergiant elliptical galaxy and the central dominant galaxy of the abell 85 galaxy cluster in the constellation cetus, about 700 million light years from earth. [ 1] it was discovered c. 1937 by erik holmberg. [ 2].
Holmberg 15a Muse Galaxy Cluster Abell 85 Ultramassive Black Hole Holmberg 15a’s ultramassive black hole is estimated to have a mass of 40 billion times that of the sun. “this is the most massive black hole with a direct dynamical detection in the local universe,” the researchers said. “it is a factor of two larger than black holes in ngc 4889 (21 billion times that of the sun) and ngc 1600 (17. ♺ details holmberg 15a is a supergiant elliptical galaxy, some 700 million light years from earth. It’s titled “ a 40 billion solar mass black hole in the extreme core of holm 15a, the central galaxy of abell 85. the paper is based on only two nights of observations with the multi unit. The black hole in the holmberg 15a galaxy has a mass nearly 40 billion times larger than the sun and is the biggest to be measured using a method called direct dynamical detection.
